EZRAC. BULL, OF NAUGATUCK, CONNECTICUT, ASSIGNOR OF ONE-HALF TO CHARLES E.

GRAHAM, OF WEST HAVEN, CONNECTICUT.

MACHINE FOR GALVANIZING CHAIN.

To all whom it may concern:

Be it known that I, EZRA C. BULL, a citizen of the United States, residing at Naugatuck, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Machines for Galvanizing Chain and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1 a top or plan view of a machine for galvanizing chain constructed in accordance with my invention. Fig. 2 a side view of the same with a portion of the frame broken away. Fig. 3 a top or plan view of a modified form of shaking device. Fig. 4 a broken side view of the same.

This invention relates to an improvement in machines or attachment for galvanizing chain.

In the usual process of galvanizing chain the surplus spelter is removed from the chain by shaking it manually. Hence the length of chain possible to galvanize at one time is limited to the amount which an operative can handle; consequently large chain must be galvanized in comparatively short lengths.

The object of this invention is to provide a mechanical device through which the chain passes from the spelter kettle which will shake the chain so as to remove surplus spelter and so that any length of chain can be galvanized; and the invention consists in the construction hereinafter described and particularly recited in the claim.

In carrying out my invention I employ a frame 2 of suitable size and conveniently arranged to be supported above or at one side of a galvanizing kettle. As herein shown this frame 2 supports longitudinal bars 3 and 4 which project beyond the frame and at the inner end support a roller 5, and at their outer end acorresponding drawing roller 6, while supported from the bars within the frame and depending therefrom is a depressing roller 7. The drawing roller 6 is mounted on a shaft 8 carrying a driving pulley 9. At the forward end the frame is eX- tended to support a shaft 10 carrying a small pulley 11 which is driven by the belt from a Specification of Letters Patent.

large pulley 12 on the shaft 8. Upon the inner end of the shaft 10 is a crank 13 which is coupled by a link 14 with a slide 15 mounted upon an inwardly extending arm 16 supported by the forward bar 17 of the frame. The inner end of this slide is below the drawing roller 6 and carries an eye or ring 18 through which the chain passes. The chain 19 from the kettle passes up over the roller 5 down under the roller 7, up over and once around the drawing roller 6 and down through the ring 18.

The device being set in motion the chain as it is drawn from the kettle passes through the eye 18 and this eye through its connections is moved back and forth very rapidly so that the chain is shaken in substantially the same way as it would be shaken by hand, and so that all surplus spelter is removed. Instead of moving the eye back and forth as described, the eye may be pivoted to the arm 16 as shown in Fig. 3 of the drawings, the eye having an extension 20 which is connected by a link 21 with an eccentric 22 on a shaft 23 which shaft carries a pinion 24 meshing with a pinion 25 on a pulley shaft 26 carrying a pulley 27 corresponding to the pulley 11 and driven by the large pulley 12. In this construction the eye is given a motion back and forth so as to shake the chain in the same way as in the construction first described. It is therefore evident that various means may be provided for operating the eye and I therefore do not wish to be understood as limiting the invention to the exact construction shown.

I claim 1. In a machine for galvanizing chain, the combination with a frame, rollers supported thereby including a drawing roller, an eye ar ranged below the drawing roller, and means for moving the eye transversely to the movement of the chain substantially as described.

2. In a machine for galvanizing ohain, the combination with roller supporting frames, of rollers mounted therein including a drawing roller, means for driving said drawing roller, a slide arranged below the drawing roller and carrying an eye, and means for moving the eye back and forth in a horizontal plane, substantially as described.

3. In a machine for galvanizing chain, the combination with a frame supporting'longitudinal bars, three rollers supported thereby, specification in the presence of two subscribmeans for driving one of said rollers, a transing witnesses.

versely movable eye arranged below the r driven roller, a slide by which the said eye is EARA BULL 5 carried, a crank connected with said slide, lVitnesses:

and means for driving said crank. FREDERIO C. EARLE,

In testimony whereof, I have signed this CLARA L. l/VEED.
